2005 Envoy blower problems

Original problem--blower stopped working (suddenly...not a slow death)
Compressor still active and OK
Replaced the blower motor, resistor, and resistor connector.
Blower still not functioning.
Checked the voltage at the blower switch (behind speed dial/knob). Brown and green wires respond but each motor speed wire doesn't respond on voltage meter. Have also checked voltage of resistor and it doesn't respond either.
Advice?

UPDATE:::
Just loosened/lowered the blower motor a bit.
Now speeds 1-4 work. Advice for speed 5?

Usually caused by the blower relay/module up behind the glove box on the evap case.
